Description

FIELD OF THE INVENTION

[0001] The present invention relates to a pull rope unit for a training device and a corresponding training device. It thus relates to the field of training devices, as a pull rope arm according to the invention is generally intended to be used for physical training. Strength training can be performed by pulling on one end of a rope, which is guided through the pull rope arm. Strength training in which the arm itself is moved is also possible. However, the pull rope arm can also be used for other purposes.BACKGROUND OF THE INVENTION

[0002] A wide variety of training methods and equipment are known. Some of these are optimized for use in sports facilities, such as commercial gyms. Other training equipment, which is usually lighter and less expensive but also offers a lower range of performance, is designed for home use.

[0003] U.S. Pat. No. 6,669,607 B2 describes a training device that can be used for weight training. The weight is not moved freely, but is guided by two pull ropes. The pull ropes are in turn guided by arms. These arms are movable around vertical axes. This allows the distance between the ends of the arms to be changed horizontally. The disclosed training device enables modified dumbbell training. However, it does not allow for great variability in the selection of exercises.

[0004] US patent application 2014 / 0121071 A discloses a training device with a pull rope. The user works against movable weights. The pull rope is guided over a pulley, which in turn is guided on an arched vertical bar. The training device allows a detailed strength exercise to be performed with the pull rope.

[0005] However, it also appears to be optimized for only one type of muscle exercise. For a gym, it seems feasible to set up a large number of such specially optimized training devices, but this is generally not possible or attractive for home use.

[0006] U.S. Pat. No. 11,369,833 B2 discloses another apparatus in which training is performed by pulling on a rope. The counterweight here is provided by round weight plates. Such weight plates are often used for dumbbells and are therefore usually available in gyms and at home. They can form a weight unit or a weight block. Weight blocks are often formed from rectangular or cuboid weights. The pull rope used to work against the weights is guided over a roller that is adjustable in height. This allows for increased, but not yet high, variability during training. In particular, it is not intended to train both sides of the body at the same time, or at least not to do so with two pull ropes.

[0007] Incidentally, a separate frame is required, which is only useful for this device.

[0008] Utility model DE 203 03 096 U1 discloses a training device for the human body. This device is intended to serve as a butterfly station. Accordingly, two arms with pads are provided with which these exercises can be performed.

[0009] The arms are connected to weights via a metal cable. The metal cable is guided over several pulleys. One of these pulleys is connected to an adjustment mechanism, which comprises two adjustment parts that interlock like telescopic tubes. Accordingly, the position of this pulley can be changed. Openings spaced apart from each other are provided to lock the two adjustment parts in different positions. In many cases, this principle certainly allows for convenient adjustment. However, the adjustment may be perceived as inconvenient, especially if frequent adjustments are required for a particular type of device. Furthermore, considerable force must be exerted to make this adjustment. Both the weight of the adjustment part itself and, depending on the direction of adjustment, the weight of the exercise weights connected to the metal cable play a role here.

[0010] The present invention aims to provide an efficient pull cable unit with which an attractive training device can be manufactured that is also particularly suitable for home users.

[0011] This task is solved by a pull rope unit according to claim 1. Advantageous further developments are specified in the subclaims.DETAILED DESCRIPTION

[0012] The invention relates to a pull rope unit for a training device. This pull rope unit will usually be permanently mounted on a training device, and in this respect the invention also relates to a training device with this pull rope unit. However, the pull rope unit can also be sold separately and can also be removed from the training device. The pull rope unit should in particular comprise a pull rope. This can be solid or multi-stranded in the manner of a stranded wire. It can also be braided or twisted accordingly. The pull rope is usually made of metal and comprises a large number of strands. Other materials are also possible, such as plastics or carbon fibers. This pull rope should be connected to a force unit. The force unit provides the force to be used for training purposes. For this purpose, the force unit may comprise a spring or an electromechanical unit or, in individual cases, a motor. Typically, the force unit comprises a plurality of weights, for example a square weight block, in which a different number of weights can be selected to apply a specific force.

[0013] The pull rope unit should also have a length adjustment unit that allows a longer or shorter pull rope section to be used for training. This length adjustment unit should be able to assume at least a first fixed position in which the pull rope length usable for training is fixed. It should also be able to assume an adjustment position in which the pull rope length usable for training can be changed. The pull rope unit should be connectable to a training unit. Handles are particularly suitable as training units. However, levers can also be used for training, on which the force of the force unit is to act. Suitable connecting means, such as carabiner hooks, can be provided for connection.

[0014] The pull rope unit should be able to be firmly connected to the training device at one point. This is the anchor point. The length adjustment unit should itself accommodate the end of the pull rope to be anchored. The length adjustment unit should also include a receiving unit that can accommodate a section of pull rope.

[0015] In other words, the pull rope should be firmly connected to the training device at one point.

[0016] In the context of the present invention, it has also proven useful for the pull rope unit to be designed so that the usable rope length can be changed continuously or can be changed with a large number of steps, which is practically equivalent to continuous adjustment; for example, there could be more than 10 or even more than 20 possible usable pull rope lengths. It is also conceivable that there are more than 100 possible pull rope lengths.

[0017] A pull rope unit in which a pull rope can connect the force unit directly to the training unit is also of interest.

[0018] A pull rope unit in which a pull rope can connect the force unit directly to the training unit is also useful. Accordingly, the pull rope can, for example, run from the weight block of the force unit to a hook that can be connected to a training unit. It is also conceivable that one end of the pull rope is anchored at a fixed point and is guided from this point via a movable roller which is connected to the force unit.

[0019] It is also useful if the receiving unit comprises a device in which a section of the pull rope can be stored well, in particular in a predetermined arrangement. For example, the pull rope can be stored there in the form of loops or eyes and then made available when the effective pull rope needs to be extended. It is generally advantageous if the receiving unit comprises a pulley. The pull rope can then be wound around the roller. It is advantageous if only one roller and one winding direction are provided. Rope shortening by rolling in two different directions, for example once clockwise and once counterclockwise, makes the length reduction more complex and the device more mechanically vulnerable.

[0020] It is also useful if the length adjustment unit has a spring force that can shorten the cable. For example, a roller can be preloaded against the force of a coil spring, thereby shortening the cable, but allowing it to be lengthened against a slight spring force.

[0021] A pull rope unit with a centrifugal brake on the length adjustment unit is also useful. It may be that the adjustment of the training device allows manual assistance and dangerous situations can arise if this is not guaranteed. If a force is applied that causes a sudden and significant extension of the pull rope, the centrifugal brake can suppress this. The centrifugal brake can be designed in various appropriate ways. One practical design, for example, is a detent lever that is pulled outward by centrifugal force and, when this happens, prevents further elongation of the cable—for example, further unwinding of the cable from a reel. In order to be effective only when sufficient centrifugal force is applied, such a lever can be subjected to a suitable spring tension.

[0022] It is also practical in the context of the present invention if the pull rope unit is incorporated into a training device. Such a training device may comprise a frame and an attachment, in particular at least one training arm mounted on the frame. It is then appropriate for the pull rope unit to connect a holder for a training unit (e.g., a handle or a movable arm) to a weight block, and for this holder to be provided at the end of the training arm remote from the frame.

[0023] A pull rope unit that is integrated into a training device is also useful, whereby this training device has a height-adjustable training arm and the pull rope unit is designed so that the force of the force unit does not counteract the height adjustment of the movable arm. For this purpose, it is useful if the pull rope unit is guided in such a way that the same pull rope length is released at one end of the pull rope during height adjustment and taken up at the other end of the pull rope. In this way, effortless height adjustment can be achieved, whereby “effortless” refers to the force unit, typically a weight block, and not to the absence of friction.

[0024] Within the scope of the present invention, a pull rope unit provided with a training device with a weight block is also useful, in which the weight block is guided on a movable roller. It is then also useful if the movable roller is arranged between a first pull rope section and a second pull rope section and the training device provides first pull rope guides over which the first pull rope section is guided to the end of the movable arm remote from the device, and the training device provides second pull rope guides over which the second pull rope section is guided to the end of the movable arm close to the device. In this situation, it is also useful if the length adjustment unit is provided at the end of the movable end closest to the device. It can also serve as an anchor point for the pull rope there and connect it firmly to the end of the movable arm closest to the device or to a component connected to it. This design allows for effortless height adjustment and also allows the force to be transmitted in a very controlled manner via a relatively long cable.

[0025] Furthermore, this arrangement ensures that the length adjustment unit is not subjected to excessive stress even during jerky movements, as even a metal cable has a certain degree of elasticity.

[0026] The present invention may also generally refer to a pull rope unit for a training device with a height-adjustable training unit, wherein the pull rope unit comprises a pull rope and a force unit, and it may also refer to a training device with a pull rope, height-adjustable training unit, and a force unit, wherein the pull rope unit or the training device is provided with a length adjustment unit connected to the height-adjustable training unit. In this way, the length adjustment unit can provide an anchor point on the movable arm. The height-adjustable training unit can be a movable arm as described below.

[0027] The present invention may also refer generally to a pull rope unit for an exercise machine or exercise apparatus in which at least one weight is guided on a movable pulley and, if necessary, other features described herein are implemented.

[0028] The present invention also relates to a method for using an exercise machine, comprising the following steps:

[0029] a) Move the length adjustment unit to an adjustment position where the length of the pull rope that can be used for training can be changed.

[0030] B) Connecting a training unit to the pull rope unit

[0031] c) Moving the length adjustment unit into a fixed position in which the pull rope length usable for training is fixed.

[0032] The process can be usefully supplemented by a step in which the height of the movable arm is changed and the length adjustment unit is moved along with the arm.

[0033] Further features and advantages of the invention are apparent from the drawings and the accompanying description below. The figures and accompanying descriptions describe features of the invention in combination.

[0034] However, these features may also be included in other combinations of an object according to the invention. Each disclosed feature is therefore also to be regarded as disclosed in technically meaningful combinations with other features. Some of the illustrations are slightly simplified and schematic.

[0041] FIG. 7 shows an enlarged side view of part of the pull cable unit according to the invention, in particular also the cable adjuster.

[0042] FIG. 8 shows a cable adjuster in perspective view.

[0043] FIG. 9 shows a sectional view of the rope adjuster

[0044] FIG. 10 shows another sectional view of the cable adjuster

[0045] FIG. 1 shows two brackets according to the invention in a perspective view. These support pull rope arms and, together with these, form attachments that are mounted on a training rack. The first attachment 10A is visible on the right, and the second attachment 10B is visible on the left. The first attachment 10A is mounted on the first front post 12A, and the second attachment 10B is mounted on the second front post 12B. The posts 12A and 12B, together with the rear posts 14A and 14B, form four posts of a training frame. These posts are connected by upper crossbars 16 and lower crossbars 18. Training frames of this type are widely used and also popular with home users.

[0046] The first attachment 10A comprises a pull cable arm or movable arm 20A. This is mounted on a joint 22A. The joint is mounted on the first post 12A with the bracket in the form of the sleeve 24A.

[0047] The attachment 10A also has a handle 26A. This handle allows for a variety of physical exercises, but does not need to be mounted. The attachment 10A also has a pin 28A. Additional weight plates can be attached to this pin, but this is not necessary. The pin 28A does not need to be mounted on the arm 20A either.

[0048] At the end of arm 20A there is a pulley 30A, which can guide a pull rope 32A. The pull rope 32A is guided from pulley 30A along the training rack to the weights 34A.

[0049] The training frame also has lower front arms 36A and 36B. These allow for an alternative guide for the pull rope. The rope guides 38A and 38B are provided for this purpose. The training frame also has lower upper arms 36C and 36D. These allow for yet another alternative guide for the pull rope. Cable guides 38C and 38D are provided for this purpose.

[0050] FIG. 2 shows the training device in a front view. The right front post 12A and the left front post 12B are visible. An upper crossbar 16 and a lower crossbar 18 are visible. Attachment 10A is mounted on the right front post 12A, which provides the movable arm 20A. Attachment 10B is mounted on the left front post 12B, which provides the movable arm 20B. The attachments are each mounted on support plates, plates 40A and 40B. Side panels are used for mounting, namely the outer side panel 42A and the inner side panel 42C for the movable arm 20A. Similarly, the outer side panel 42B and the inner side panel 42D are used for the movable arm 20B.

[0051] FIG. 3 shows the training device in a side view. The view shows the right front post 12A and the right rear post 14A. Towards the front, these posts and unspecified cross struts are extended by the lower arm 36A and the corresponding upper arm 36C. These arms each carry rope guides, the rope guide 38A at the bottom and the rope guide 38C at the top. The movable arm 20A of the attachment 10A is held by the horizontally extending axle 44. The arm 20A can move in a vertical plane around this axle. The post 12A also lies (at least partially) in this plane.

[0052] The bracket in the form of the sleeve 24, which connects the attachment 10A to the post 12A, can be moved up and down on this post. It can be connected to various recesses in the post 12A for fixing purposes. The locking pin 46 is provided on the sleeve 24 for this purpose. Further height adjustment is provided by the row of holes in the side panel 42A. This row of holes allows the arm to be fixed at a specific angle. The arm then falls down to the specified position and can be lifted from this position. Alternatively, it would also be possible to limit the upward angle movement of the arm. The row of holes in the side panel 42A can also be used to fix the upper angle position of the arm. The arm can then be moved downwards from this position for appropriate muscle exercises.

[0053] This illustration also clearly shows the guide for the pull cable 32. A pull cable section 32A is connected to the weight block 34A. The pull cable is guided over the upper deflection roller 48, among other things. From this deflection pulley, the pull rope is guided to the feed roller 50, which is located on the cuff 24 and can guide the pull rope to the movable arm 20A. Another section of the pull rope is guided upwards by the lower deflection pulley 52 (not visible as a component in this side view, but recognizable by its function).

[0054] This section of the pull rope is also guided to the sleeve 24. By providing at least one upper deflection roller 48 and at least one lower deflection roller 52, it is possible to form a rope loop in which a pulling force of equal magnitude acts upward from the upper deflection roller and downward from the lower deflection roller 52. By applying equal tensile forces to the sleeve 24 from above and below, it is possible to move the sleeve up or down along the post 12A with very little resistance.

[0055] Within the scope of the present invention, a rope adjuster is to be provided in the area of the sleeve 24, which can be integrated into the sleeve 24. It is symbolically represented as L in this side view and is shown and discussed in more detail for another embodiment.

[0056] FIG. 4 shows a training device in a perspective view. Only the essential elements of the device are marked with reference symbols. The posts 12A, 12B, 14A, and 14B provide a frame. Two attachments according to the invention are mounted on this frame, attachment 10A on the right and attachment 10B on the left. The movable arms 20A and 20B extend from the cuffs 24A and 24B, respectively. At the end of the arms, the handle 64A and the handle 64B are connected to the pull rope 32A. The handle 64A is used to pull the weight 34A upwards against a pulling force, and the handle 64B is used to pull the weight 34B upwards in the same way.

[0057] Both arms are movable in a vertical plane. They can be moved parallel to each other. The axes of movement of arms 44A and 44B are oriented horizontally. These axes of movement 44A and 44B are mounted approximately at chest height. The arms extend upward from these axes so that handles 64A and 64B are positioned approximately at head height or above. Both arms can be fixed in this orientation (using the perforated plates on the side panels and corresponding bolts described above).

[0058] This setup is suitable for muscle exercises in which the shoulder area in particular is trained by pulling movements from top to bottom.

[0059] FIG. 5 shows a training device with brackets according to the invention in a different configuration. The movable arms 20A and 20B are mounted on brackets in the form of cuffs 24A and 24B. The cuffs and the axles 44A and 44B provided on the cuffs are again mounted approximately at chest height.

[0060] However, this time the axes are not aligned horizontally. Accordingly, the arms 20A and 20B are moved out of the vertical planes. More precisely, the arm 20A is tilted outwards from the vertical plane marked by the posts 12A and 14A. In this case, outward means to the right, i.e., so that the distance between the user-side arm end and the other arm 20B is increased. Arm 20B is tilted in the corresponding manner, i.e., to the left. Like the arms, the axes can be fixed in this position. For this purpose, rows of holes with engaging bolts are provided.

[0061] The arms are also oriented upwards, so the handles 54A and 54B are located above the cuffs and approximately at head or shoulder height.

[0062] In this configuration, the pull rope arms mounted on the brackets allow for a different type of muscle training. Again, the handles are pulled toward the body, but the pull direction is not only from top to bottom, but also from outside to inside. Inward describes locations approximately on the center plane between the left vertical plane marked by posts 12B and 14B and the right vertical plane marked by posts 12A and 14A. Accordingly, other muscles are targeted and trained efficiently.

[0063] FIG. 6 shows a perspective view from above (similar to that used in FIG. 1) of a training device on which the pull rope unit according to the invention is mounted. The training device thus has a universally applicable frame, which in particular comprises posts 12A, 12B, 14A, and 14B, as well as two attachments 10A and 10B, which each provide arms for exercise purposes, arms 20A and 20B.

[0064] At the end of these arms, deflection rollers are provided, namely rollers 30A and 30B. The training device has a total of two pull ropes, namely pull ropes 32A and 32B. The precise course of these pull ropes in different pull rope sections is now described in more detail. It should be noted that although a pull rope can be designed as a multi-piece, it is usually designed as a single piece, so that the rope sections now described represent functional sections that make the function of the pull rope easier to explain, but cannot be distinguished as components.

[0065] For clarity, the individual sections are shown using pull cable 32A, i.e., the pull cable located on the right side of the training device.

[0066] The connecting hook 56 is provided at the end of this pull rope. This connecting hook is used to attach the pull rope to the upper arm 36C. One of the advantages of the pull rope unit according to the invention is that it can be used universally on different training devices and for different training purposes. Accordingly, the connecting hook 56 can also be connected to a handle 54, as shown in the previous illustrations.

[0067] In the training mode shown here, connecting the connecting hook 56 to the upper arm 36C means that the arm 20A must move downward against a force. This force is applied by the weight unit 34A. The pull rope section that connects to the connecting hook 56 and runs outside the arm 20A is referred to here as the exercise section 58. It connects the hook 56 to the end of the arm 20A where the deflection pulley 30A is provided. The pull rope continues to run inside the arm. This part is referred to as the feed section 60. The feed section 60 is led out of the rear of the arm and guided upwards via the deflection pulley 50. There, this section is guided to the weight unit 34A via outer deflection pulleys 62 of the training frame. The weight unit 34A is connected to the pull rope 32 by the movable pulley 64.

[0068] This movable pulley 64 separates the feed section 60 from the holding section 66. The holding section of the pull rope 32 is guided back toward the attachment 10A via internal pulleys 68 on the frame. It is first guided into the lower part of the frame and deflected upward via the pulley 52. The end of the pull cable is now connected to the cable adjuster 70, where it has its anchor point.

[0069] As already explained with reference to FIG. 3, it is therefore possible to adjust the height of the attachment part 10A without applying force. When the attachment part 10A is moved downwards by 10 cm along the post 12A, 10 cm more cable length is available along the retaining section 66. This rope length is deflected by the movable 64 and is then also available as additional rope length in the feed section 60. This means that exactly the required 10 cm of rope length is available to move the boom 10A downwards in the area between the upper outer deflection roller 62 and the deflection roller 50.

[0070] The rope adjuster 70 not only forms the anchor point for the pull rope- or more precisely for the end of the holding section 66 of the pull rope 32A-but also allows the rope length to be adjusted. A strength exercise can be performed on the training device shown by moving the arm 10A from top to bottom. The pull rope provides a force in the exercise section 58 that counteracts the downward movement. Such an exercise can be performed, for example, while lying on a training bench. To do this, it is necessary to move the handle 26A to a suitable starting height for the exercise. Of course, this should be done with as little force as possible and in any case not against the force of the weights 34A. If the handle 26A needs to be moved further down to find an ideal starting position, more rope length is required (provided that, as shown, the connecting hook 56 is connected to the arm 36C). This rope length for convenient adjustment of the height of arm 10A can be obtained by adjusting rope adjuster 70 so that it allows extension of rope 32A.

[0071] For this purpose, the rope adjuster 70 has a roller around which the rope is wound and can be unwound as required. To enable the exercise to be performed after unwinding a further section of rope, the rope adjuster 70 must be fixed again. Once it is fixed, the arm 10A can only be moved downwards against the weight force applied by the weight unit 34. It can be seen how, particularly in the configuration of the training device shown, it is advantageous not only to be able to move the arm along the post 12 without weight, but also to be able to adjust its angular position in space without weight.

[0072] FIG. 7 shows a side view of the rope adjuster 70 according to the invention. The view shows the left front post 12A. The attachment 10A is fastened to this post by means of the sleeve 24. The sleeve 24 can move up and down on the post. The rope adjuster is connected to the holder 72 with the sleeve 24. Therefore, the rope adjuster 70 is moved up and down together with the sleeve 24. Since the rope adjuster also serves as an anchor point for the end of the pull rope, i.e., in particular, fixes the end of the holding section 66, the pull rope is connected to the movable sleeve 24 in this manner. The rope adjuster 70 has a turntable 74, which limits it laterally and is designed to be rotatable. This has a knob 76, which can be used to turn and lock the disc 74. The mechanism is explained in more detail in the following figures.

[0073] FIG. 8 shows the rope adjuster 70 in a perspective view in an unassembled state. The view shows the outer turntable 74, which can be moved and locked into place using the knob 76. The turntable can also be operated using the central control knob 75. A roller 80 is located between the elements of the bracket 72. Sections of the pull rope can be rolled up or unrolled onto this roller. Both operations can be performed conveniently and in a controlled manner using buttons 76 and 78.

[0074] FIG. 9 shows a sectional view through the rope adjuster 70 from a similar perspective. This sectional view shows the elements located beneath the turntable 74 shown previously. The buttons 76 and 78 are also visible. The locking lever 82 is also visible here. It nestles against the central control button 78 and, in this position, allows unhindered operation of the roller 80, in particular the unwinding of a pull rope. However, this locking lever 82 acts as a centrifugal brake. When the roller moves quickly, the lever 82 moves outward. It then engages with its end in the locking mechanism 84. This prevents the roller from being locked and the pull rope from being unwound further. The centrifugal force can be counteracted by a suitably dimensioned coil spring, which is inserted into the holder 86 and normally holds the centrifugal brake in a position where manual operation of the roller is possible without obstruction.

[0075] However, the locking lever 82, as part of a centrifugal brake, is of considerable importance. Especially when the pull rope is connected to a heavy element—such as the arm 20A—it is important to prevent the pull rope from accidentally unrolling in an uncontrolled manner. Such unrolling could result in injuries caused by a falling exercise element, for example, the solid arm 20.

[0076] FIG. 10 shows the rope adjuster 70 in perspective view from the opposite direction. The view here is therefore of the side opposite the turntable 74. Accordingly, the buttons 76 and 78 point away from the viewer. This sectional view also shows a partially open side of the rope adjuster 70. The side part 88 connected to the roller 80 can be seen here. This side part is in turn connected to the spiral spring 90. The coil spring can be used to automatically turn the roller in one direction. It is useful if the spring causes a rope to roll up. This prevents the rope from hanging loosely. This alone reduces the risk of injury. In addition, the precise adjustment of a training device with a taut rope can be achieved more quickly.

[0077] The pin receptacles 92 are also visible from this perspective. These can accommodate a locking pin connected to button 76. The closely spaced pin receptacles 92 enable very precise adjustment of the roller. The interaction of a pin with the pin receptacles also allows the roller to be securely fixed in place, enabling it to withstand high forces.

[0078] Overall, it can be seen that the present invention provides a simple means of creating a practical training device. The pull unit according to the invention enables safe and comfortable training, even when heavy weights are used.LIST OF REFERENCE MARKS10 Bracket
